8.2 Mode
The sensor configuration is preset at the factory before the sensor is delivered. This device
setting can then be optimized to suit the process.
Measure mode and parameters:
The following sensor settings can be changed
• Measure mode A - OnRequest (only in network mode for calling up measured values via the
serial interface for calibration purposes).
• Measure mode C - Cyclic (default setting for sensors with cyclic measurement).
• Average time, reaction speed of the measured values
• Calibration (when different materials are used)
• Filter function
• Precision of a single value measurement
Each of these settings is retained even after the sensor is switched off, i.e. the setting is
saved to the non-volatile memory of the sensor.
8.2.1 Operating mode
The sensor is supplied from the factory with the CA mode for general process applications. Six
different operating modes are available in the C mode, depending on the application.
• CS mode (Cyclic-Successive)
For very short measurement cycles in the seconds range (e.g. 1 to 10 seconds) without
averaging and without filter functions, and with up to 100 measurements per second
internally and a cycle time of 250 ms at the analog output.
• CA mode (Cyclic Average Filter)
Standard averaging for relatively fast but continuous measurement processes, with simple
filtering and an accuracy of up to 0.1 %. The CA operating mode is also used to record raw
values without averaging and filtering to subsequently be able to analyze the measured data
and identify the best operating mode.
• CF mode (Cyclic Floating Average with Filter)
Floating average for very slow and continuous measurement processes, with simple filtering
and an accuracy of up to 0.1 %. Suitable for applications on a conveyor belt etc.
• CK mode (Cyclic with Boost Filter)
For complex applications in mixers and dryers
• CC mode (Cyclic Cumulated)
With automatic totalization of moisture quantity measurements in one batch process if no
PLC controller is used
• CH mode (Cyclic Hold)
Standard operating mode for applications in the construction industry. Similar to the CC
mode, but with filtering and without totalization. The CH mode is ideal for very short batch
times as low as 2 s if the sensor has been installed under the silo discharge hatch. The CH
mode performs filtering automatically. This allows drip water that forms in the silo to be
filtered out of the measured value, for example.
8.3 Calibration curve set B for grain
For the measurement of different types of grain, special calibration curves for maize, rye,
wheat, barley, soy, etc. can be saved in the sensor and can be activated via the remote display.
